The single most common rug regret is not color, not pattern — it's ordering one size too small. A too-small rug makes furniture look like it's floating and the room look smaller. Here is the short version of getting it right, room by room.
The living room rule: front legs on
Every seat in the conversation area should have at least its front legs on the rug. For most sofas-plus-two-chairs layouts that means a 45" × 72" (Medium) at minimum, and a 60" × 96" (Large) if the room is open-plan. A rug that only fills the coffee-table zone is the classic too-small mistake. Browse sizes on our washable area rugs.
Bedroom: 18–24 inches of landing zone
You want bare-foot rug on each side of the bed. Either run a large rug under the bottom two-thirds of the bed, or place a runner along each side. A round rug (48"–60") also works beautifully beside a bed or under a reading chair.
Dining room: add 24 inches all around
Measure the table, then add at least 24" on every side so chairs stay on the rug even when pulled out. For round tables, a round rug 72"–79" across is the natural match.
Hallways and kitchens
Leave 4–6" of floor visible along each side of a runner. Full length charts for every product we make — area rugs, round mats, runners and doormats — are in the size & measurement guide.
The painter's-tape trick
Before ordering, outline the candidate size on the floor with painter's tape and live with it for a day. It takes five minutes and has saved thousands of returns industry-wide. When in doubt between two sizes, go bigger — nobody has ever complained a rug made the room feel too generous.
